Adistance of 150 km was covered by a motorcyclist traveling at a average speed of 75 km/h by a bus 60 km/h a truck at 50 km/h and a bicyclist at 20 km/h how much time did it require to travel the entire distance

The time required to travel the entire distance is 2.93 hour.

Step-by-step explanation:

Given that,

Distance = 150 km

Speed of motorcyclist = 75 km/h

Speed of  bus =60 km/h

Speed of truck = 50 km/h

Speed of bicyclist = 20 km/h

We need to calculate the average speed

Using formula of average speed

Put the value into the formula

We need to calculate the time

Using formula of speed

Where, D = total distance

t = time

Put the value into the formula

Hence, The time required to travel the entire distance is 2.93 hour.

the answer is a.
